New 3D Cutting PM 2.5 Activated Carbon Filter Insert, 5 Layers Pm 2.5 Filter Replaceable Protective Filter to Anti Haze Dustproof Air Pollution Large Size (24)

I like these because they fit nicely in the cloth masks that have the extra area for filters. I also like the fact they give me more protection.

So glad to finally find quality mask filters that cover your nose and mouth. We’ve received oodles of the smaller ones with masks we have purchased but if the filter doesn’t cover your mouth AND nose what good is it doing you?? Love these. A bit challenging to get situated in the mask pocket but once it is in place, it stays. Highly recommend

Very nice filter. I use them in the pocket of my cloth mask, it's a little big for my mask but i know not all cloth masks are cute from the same cloth 😂. I still use them anyways.

Although not perfect, they work pretty good for the Oakley Msk Mask. The Oakley replacements cost about $10 for 3. These are a lot more economical and they cover all exposed mesh on the Oakley Msk Mask.

I tried to save some money...I go through a lot of inserts. The Honeywell ones just fit better - they stay in place, give a little room away from nose/face. These don't quite seem big enough, and keep bumping and slipping below my nose.

No complaints here. Got exactly what I paid for. 👍

I've used these for a couple years inside of my cloth masks and have been much more comfortable than the flat options. I've been staying healthy using them too.

Thought this was a good idea as it would fit the shape of my masks, but unfortunately they are too large. I even measured the filter area before purchasing and these should have fit. Instead they bunch & wrinkle inside the area and make the mask uncomfortable to wear. I'll reorder the rectangular filters as they seem to be a better fit. These will just become trash. Waste of money!
